Abstract
In connection with the increasing anthropogenic load, it is necessary to control the content of various impurities in the atmospheric air. One of these compounds is formaldehyde, which has carcinogenic and mutagenic properties. To measure the concentration of this substance, various methods are used - chromatographic, spectrophotometric, fluorescent. As an alternative to these methods, the authors propose the use of photoacoustic detection. According to the results of comparative tests, this method should be considered suitable for use in monitoring atmospheric air.
